extract features from image database in simpleCV

Question

I am new to python, therefore I need some help: AIM: I have an image database containing 10 images. I want to use a hue feature extractor to extract the hue from each image and store it in a list and compare the list with hues from other images not belonging to the databae Now this code works fine for me for a single image e.g.:

print __doc__
from SimpleCV import*
from SimpleCV import HueHistogramFeatureExtractor, np
import numpy as np
    image1 = ...
    image2 = ...

    hue = HueHistogramFeatureExtractor() # define the extractor      
    x = np.array(hue.extract(image1))  # extract features
    y = np.array(hue.extract(image2))  # extract features

    xandy = np.sum(np.square(x-y)) # compare extracted features

    print xandy

    ('#######################################################')
    Of course avoiding to write each image seperatly from a database I tried: 

    imageDatabase = "/.../dir/car/" #load image database
    car_images = ImageSet(imageDatabase)
    hue = HueHistogramFeatureExtractor() # define the extractor 
    car_hue = [hue.extract(car_images) for c in car_image] # extract hue features from image database???  
    print hue # print hue feature list

Do I am on the right track? Please give me direction to work to.

So the hue histogram extractor extracts a histogram of hues, not a single average hue value (which it appears to be what you want to do). Have you tried meanColor? Also if you use the SimpleCV help forum we might be able to better support your questions.
